11.5.6 MAC-Process: LAC
This process displays on its console the message telegrams to
and from connected LACs.
At the same time it fowards important information from the
DMS and MAC to the LACs, so that these are capable of making
basic access control decisions on their own. Only system-wide
decision criteria are held on and decided on by the MAC.
The LAC process has the following responsibilities:
– Communications with all connected LACs.
– Gerneration of status information pertaining to all LACs,
readers and, if necessary, devices connected to LACs.
– Program downloads for LACs and readers.
– Initialization of LACs with their required parameters.
– Receiving and forwarding of event messages generated by
LACs.
– Receiving of access control requests from LACs
(authorization checks etc.). The forwarding of requests via
the central Messenger to the responsible MAC processes
and returning results to the LACs.
